Description

Technical Field

[0001] This invention relates to an installation device and method for anchorages, anchor plates, and steel strands, and more particularly to an installation device and method for anchorages, anchor plates, and steel strands used in bridge prestressing tensioning. Background Technology

[0002] During the prestressing process in bridges, anchorages need to be installed between the anchor plate and the steel strands. However, existing installation devices for anchorages between the anchorages and the anchor plate and steel strands in bridge prestressing tensioning lack a specific installation method. Currently, the anchorages are manually placed onto the steel strands and then manually installed. This process is hampered by shallow anchor plate slots, the influence of the steel strand angle, the weight of the anchorage and hydraulic jack during tensioning, and limited working space. These limitations prevent the anchorages from accurately falling into the anchor plate slots during tensioning, leading to edge compression and eccentricity. This results in uneven stress on the anchor plate, negatively impacting the prestressing loading effect.

[0003] This invention, by providing positioning and support for anchors in a welded state, effectively explores and studies the technical problems of edge pressing and eccentricity caused by manually placing anchors on steel strands and installing them on the steel strands.

[0058] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0059] A method for installing an anchorage, anchor plate, and steel strand for prestressed bridge tensioning includes the following steps: During prestressed bridge tensioning, the anchorage is fitted onto the steel strand. The operator holds the handle 3, aligning the inner end of the support plate 21 with the anchorage's installation position. The base plate 1 is placed on the anchor plate, and bolts are inserted into the mounting holes 13, causing the mounting holes 13 to rotate on the anchor plate. This attaches the strip plate 11 and the arc plate 12 to the anchor plate. The anchorage is then placed on the support plate 21, with its outer end contacting the telescopic end of the prestressed bridge tensioning cylinder, thus positioning the tensioning cylinder... In the extended state, the prestressing tensioning cylinder pushes the anchorage inward on the support plate 21, installing the anchorage on the anchor plate. The anchorage and anchor plate are then connected by welding. Next, the steel strand is connected to the telescopic end of the prestressing tensioning cylinder, putting the cylinder in a contracted state to tension the prestressing. After tensioning, the steel strand is separated from the telescopic end of the cylinder, causing the mounting hole 13 to rotate in the opposite direction on the anchor plate. The bolt is then removed from the mounting hole 13, separating the base plate 1 from the anchor plate.

[0060] When the sliding block 5 moves in the dovetail groove of the guide rail 4, the pressure rod part 64 is placed on the outer end of the anchor. The operator holds the second inclined rod part 63 with his hand, and the cross rod part 61 rotates on the pin located on the sliding block, which drives the first inclined rod part 62 to swing. The pressure rod part 64 pushes the anchor to move inward on the support plate part 21.

[0061] In verifying this invention, the inventors abandoned the existing technical features that involved manually placing the anchors onto the steel strands and then installing them, which would result in edge pressing and eccentricity. Instead, they first proposed a technical feature that provides positioning support for the anchors in the welded state. This resulted in the first unexpected technical effect: ensuring the anchors were positioned and installed under external mechanical force. The second unexpected technical effect: ensuring the regular distribution of the steel strands and preventing chaotic phenomena. The third unexpected technical effect: preventing the anchor plate from shifting during bridge prestressing tensioning.

[0062] In a second embodiment of the present invention, the base plate 1 and the guide plate 2 are connected to each other in a manner that positions and supports the anchor in the welded state.

[0063] In this embodiment, the guide plate 2 is connected to the base plate 1 in an arc-shaped manner to support the moving anchor.

[0064] In this embodiment, a first accessory device is also included and disposed on the substrate 1. The first accessory device is configured as a handle 3.

[0065] In this embodiment, a second accessory device is also included and disposed between the base plate 1 and the guide plate 2. The second accessory device is configured to include a guide rail 4, a sliding block 5 and a pressure rod 6.

[0066] The second embodiment of the present invention is based on the first embodiment.

[0067] In the second embodiment of the present invention, the steps are as follows: the base plate 1 enables the guide plate 2 to be placed on the anchor plate, the guide plate 2 enables the moving anchor to be arc-shaped supported, and the anchor in the welding state is positioned and supported.

[0068] The second embodiment of the present invention is based on the first embodiment.

[0069] This invention has the following characteristics:

[0070] 1. Due to the design of base plate 1 and guide plate 2, the guide plate 2 is placed on the anchor plate through base plate 1, and the guide plate 2 provides arc support for the moving anchor and provides positioning support for the anchor in the welding state. This solves the technical problem of edge pressing and eccentricity caused by manually putting the anchor on the steel strand and then installing the anchor on the steel strand. Therefore, the prestressing loading effect is improved.

[0071] 2. The design of handle 3 enables the operator to hold the substrate 1 by hand.

[0072] 3. Due to the design of guide rail 4, sliding block 5 and pressure rod 6, the anchor can be moved and pressed.

[0073] Other technical features that connect the base plate 1 and guide plate 2, which are used to position and support the anchor in the welded state, are also embodiments of the present invention. Furthermore, the technical features of the above embodiments can be combined in any way. In order to meet the requirements of the Patent Law, the Patent Implementation Regulations and the Examination Guidelines, all possible combinations of the technical features in the above embodiments will not be described.

[0074] The above embodiments are merely one implementation of the installation device and method between the anchorage, anchor plate, and steel strand for prestressed tensioning of bridges provided by the present invention.
